Lucas' second signature bar with Prime is lighter and stronger thanks to the implementation of butting. Butting means that the internal walls of the handlebar vary in size and will be thicker where strength is needed, and thinner where it can be to save weight. The bar comes in two different sizes to accommodate most riders, and comes HIC ready straight out of the box! SCS can be used, but you'll have to remove the slit, or purchase an oversized bar adapter to fill in the slit.
